Do you have a USB hub attached? If not what all is connected to the Pi? And while that doesn't strike me as a power issue, what is the Amp rating of your power supply? Is it a well known brand or a generic charger?

[burhan]

Don't know about amp , i
am using laptop usb port as a power supply of pi .Mouse , keyboard and lcd is attached with hdmi port

[burhan]

here is a text for config file which i am using its works fine only 1st tym after rebooting. it starts giving different error

[burhan]

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

Just thinking out loud here, I would try a different power source, usb ports tend to only provide 500mA of current. If you're using the model B with a mouse, keyboard, and monitor then it's very possible that the pi is crashing because it doesn't have enough power.

When you say "when you reboot" how are you rebooting the pi?

[abishur]

Did you get to follow up on your issue?

[burhan]

yes sir, its a B model and i just tried to reboot with different power supplies but getting same errors ..don't know what to do
after installing wheezy and after getting into the teirminal i wrote "sudo halt" to shut it down and unplugged the power supply and after 1min i just attached the power supply and got this kind of error

[burhan]

Sir if it is crashing just because of the attachment of mouse ,keyboard and monitor then what's the solution??

[DougieLawson]

Attach the mouse and keyboard to a powered USB hub. Or get a better 5V 1.5A power supply.

[burhan]

same error with 5V 1.5A power supply . sir if it works fine on first boot then i don't think its the power issue. need your suggestion

[DougieLawson]

I think you should try a brand new SDCard.

[burhan]

sir i am using brand new sandisk 4gb card

[DougieLawson]

sir i am using brand new sandisk 4gb card

Try a new RPi.

[burhan]

means there is no solution . my pi is working well but just for 1 time boot

[DougieLawson]

You could try
sudo apt-get update && sudo apt-get dist-upgrade && sudo rpi-update
that gets all software packages updated and updates the system firmware (which has some recent fixes for SDCard corruptions).

[burhan]

ok thank you sir i;ll try this
